Mam
1)Why the pupil in ARGYLL ROBERTSON PUPIL is usually constricted?
2) Does pretectal nucles have inhibitory influence of Edinger westphal nucleus?
Please help!

You have a very valid & interesting doubt, Naveen. I am pasting the relevant portion from the link above to answer your question
“Damage to the rostral midbrain can result in AR pupils. Specifically, a lesion of the dorsal aspect of the Edinger-Westphal nucleus can interrupt the pretectal oculomotor light reflex fibers. However, the more ventrally located fibers of the Edinger-Westphal nuclei that control the near reaction are spared.
Supranuclear adrenergic fibers that inhibit the Edinger-Westphal nucleus are necessary for iris sphincter relaxation and pupil dilation. When this inhibitory pathway is disrupted, parasympathetic neurons of the Edinger-Westphal nucleus that naturally fire at a high rate can lead to sustained pupil contraction by the iris sphincter and cause miosis in AR pupils.”

​@@DrhilmiWhat is the role of her father in inverting the picture

[@muqarrabjavaid9170]

Is this dangerous

[@ophthalmologypearls]

All the situations mentioned here are serious conditions, some of which are temporary and others are permanent. What I described are just manifestations of a wide range of diseases.
